<p>PURPOSE: To accurately detect the possibility of a collision based on the predicted value of the distance secured between an obstance and a vehicle at the time of turning motion, regarding a monitoring device for a distance between vehicles. CONSTITUTION: This device is provided with an angular velocity detection means 15 detecting the angular velocity of a vehicle, a prediction means 16 performing an arithmetic operation by an expression d=(D<2> +R<2> -2DRcosθ)<1/2> -R for the relative distance D of a target, a rotary virtual radius R given by the ratio of running speed and the angular velocity and the differenceθof the rotary virtual center point in a prescribed location and the azimuth of the target and predicting the distance (d) of the target along the straight line connecting the virtual center point and the target and the prescribed location, and a decision result correction means 17 comparing the difference of the distance in a vehicle width direction of the object located on the opposite side to the virtual center point of the side part of the vehicle and the prescribed location and the distance (d) that the prediction means 16 predicts with a preliminarily determined threshold and invalidating the possibility of a collision via a detection means 14 or at the output terminal of the detection means when the former exceeds the latter.</p> |
